DESCRIPTION
– 3 mm x 5 mm MSOP PowerPAD™ Package
(DGN) · 1.4 W Into 8 W From a 5 V Supply at
THD = 10% (Typ) – TPA2010D1 Available in 1,45 mm x 1,45 mm
WCSP (YZF) · Maximum Battery Life and Minimum Heat
– Efficiency With an 8-W Speaker:
· 84% at 400 mW · Ideal for Wireless or Cellular Handsets and
· 79% at 100 mW PDAs
– 2.8-mA Quiescent Current
– 0.5-µA Shutdown Current
· Only Three External Components The TPA2005D1 is a 1.4-W high efficiency filter-free
class-D audio power amplifier in a MicroStar Junior™ – Optimized PWM Output Stage Eliminates LC
BGA, QFN, or MSOP package that requires only Output Filter
three external components.
– Internally Generated 250-kHz Switching
Features like 84% efficiency, -71-dB PSRR at 217 Frequency Eliminates Capacitor and
Hz, improved RF-rectification immunity, and 15 mm2
Resistor
total PCB area make the TPA2005D1 ideal for
– Improved PSRR (-71 dB at 217 Hz) and cellular handsets. A fast start-up time of 9 ms with
Wide Supply Voltage (2.5 V to 5.5 V) minimal pop makes the TPA2005D1 ideal for PDA
Eliminates Need for a Voltage Regulator applications.
– Fully Differential Design Reduces RF In cellular handsets, the earpiece, speaker phone,
Rectification and Eliminates Bypass and melody ringer can each be driven by the
Capacitor TPA2005D1. The device allows independent gain
control by summing the signals from each function – Improved CMRR Eliminates Two Input
while minimizing noise to only 48 µVRMS. Coupling Capacitors
· Space Saving Package
– 3 mm x 3 mm QFN package (DRB)
– 2,5 mm x 2,5 mm MicroStar Junior™
